I believe that Groupon is grossly overvalued. It owns no patents, no proprietary software or even innovative marketing. It's such a simplistic business model that it launched dozens of copycat sites and Groupon cannot outcompete them all. Eventually someone will see this and venture capitalists will quit throwing their good money after bad or better yet -- investors will stay away from this turkey.

Groupon has 70 million users. That number makes Mark Zuckerberg laugh. Facebook Deals, with access to almost 600 million users, will leave Groupon crying and bleeding in the street.
